perf probe: Add variable filter support
Add filters support for available variable list.
Default filter is "!__k???tab_*&!__crc_*" for filtering out
automatically generated symbols.
The format of filter rule is "[!]GLOBPATTERN", so you can use wild
cards. If the filter rule starts with '!', matched variables are filter
out.
e.g.:
# perf probe -V schedule --externs --filter=cpu*
Available variables at schedule
@<schedule+0>
cpumask_var_t cpu_callout_mask
cpumask_var_t cpu_core_map
cpumask_var_t cpu_isolated_map
cpumask_var_t cpu_sibling_map
int cpu_number
long unsigned int* cpu_bit_bitmap
